AbstractAbstract
[en] In the research project 'Determination of steel structures by means of ultrasound' methods are developed for the non-destructive structure characterization with scattered ultrasound. Measurements were made at about 200 steel samples with frequencies between 5 and 20 Mc/sec. In the range of 0,05 <= d/lambda <= 0,5 (d=mean grain size, lambda = wavelength of the ultrasound pulse) known theories can be applied for the quantitative grain size determination and with an accuracy of +-15% the results agree with the metallographically measured values. The best method for this is the combination of two measurements with two different frequencies. Advantages are given by the measurement of the multiple scattering which is leading to the scattering coefficient and to the grain size with one measurement only and without assumptions concerning other parameters of ultrasound propagation. A structure characterization concerning the homogeneity inside the material is possible, too, because of the time (i.e. sound path-)-dependent scattering measurement. It is able to control the structure of monophasic steels with grain sizes between ASTM 1 and ASTM 11. Today problems unsolved are the martensitic steels, the multiphasic structures

AbstractAbstract
[en] In this work, high temperature solid phase method was applied to prepare Sr2MgSi2O7:Eu, Dy blue light long-persistence materials with different contents of H3BO3. Under the condition of low H3BO3 content, it was difficult for Eu and Dy to enter Sr2MgSi2O7 lattice, impurity phase of Sr3MgSi2O8 was observed, and initial afterglow luminance of the sample was very low. With the increase of H3BO3, Sr3MgSi2O8 phase disappeared, Eu and Dy entered Sr2MgSi2O7 lattice smoothly, and the grain size as well as initial afterglow luminance of samples increased significantly. The initial afterglow luminance of the sample reached the maximum while the H3BO3 content was 10% (molar ratio). As H3BO3 content increased further, the initial afterglow luminance reduced rapidly. After detailed analysis, we consider that the key factors influencing the afterglow luminance of samples are the formation and the density of luminous unit, which is greatly determined by the Eu and Dy’s entering Sr2MgSi2O7 lattice as well as the grain size of Sr2MgSi2O7 crystal.

AbstractAbstract
[en] Commercial copper was submitted to a thermomechanical treatment in order to study its influence on the velocity of artificial green patina formation by immersion as well as on the thickness and adherence of the corrosion product formed on the underlying metal. The thermomechanical treatment enabled us to obtain samples with 9 to 60 μm grain size. The samples were submitted to an accelerated attack by immersion in an electrolytic bath in order to obtain a green patina. On the smallest grain size material it can be observed a patina with high thickness and adherence smooth texture and homogeneous morphology. From the electrochemical assays it was established that the passivity current decreases for decreasing grain sizes. These results are consistent with the minimal porosity presented by the patina morphology which increase the protecting power. The underlying material did not present localized attack.

AbstractAbstract
[en] The effects of grain sizes and sensitization on the creep behavior of AISI 304 stainless steel was investigated. The study state creep rate of sensitized specimens was always larger than that of non-sensitized ones. The carbides were precipitated on grain boundary during creep and this seemed to have an effect on steady-state creep rate. All of ruptured specimens mainly showed intergranular cracking. (Author)

AbstractAbstract
[en] Microstructure evolution in non-conserved and volume-conserved isotropic two-phase grain structures, with equal interfacial energy for all interfaces and equal volume fractions of the two-phases, is compared based on large-scale phase-field simulations. Two important observations are as follows: (1) the growth mechanism has a larger effect on the grain size distributions of the two alloys than on their grain topology distributions; (2) the growth rate and normalized grain size relation of the grains per topological class are much more scattered for the conserved system than the non-conserved system.

AbstractAbstract
[en] In the present research, the surface-melted aluminum bronze were manufactured by laser remelting technology. The microstructure and properties of the melted layers with and without using activator were investigated. With increasing laser power, the width and depth of the melted layer increased, and the grain size of the melted layer became coarser due to the higher heat input and larger molten pool volume. Under the same conditions (i.e. laser power of 1000 W), the width and depth of the melted layer could be reduced and increased, respectively, with the use of the activator. In particular, the depth of melted layer increased by nearly 50%. Furthermore, to obtain the same penetration of the melted layer, the addition of the activator could reduce the heat input, which led to the decrease of grain size. The relatively small grain size and high dislocation density could improve the hardness and tribological behavior of the melted layers. (paper)

AbstractAbstract
[en] Surface sediment samples from the mangrove forest of Setiu river were analyzed for the grain size analysis in order to understand better the accretion processes in the mangrove environment. There is a significant (P<0.05) relationship between sediment characteristics with the seasonal changes with a decreasing mean particle size occurring during monsoon seasons. Thhe accretion rate in this study was determined using 230Thexcess and an average accretion rate of about 0.61 cm yr-1 was obtained. Those fairly high average accretion rates obtained indicating that this mangrove may be still prograding and in an immature stage with an estimated age of 163 years. (author)
